Install error in Ubuntu 20.04

[zhanglab2008]

Hi team,

Congratulation on the new pipeline. However, I spent a day trying to install desc on my ubuntu server (20.04, amd64) but it failed. Here are my attempts:

1. I created a new conda environment and install python 3.5.4 on my server. Then I installed tensorflow 1.7.0 in the new env. Then I install desc per the tutorial. Everything looked fine. However, when I ran desc.run_desc_test(), it failed with error
   ImportError: ('Failed to import pydot. You must pip install pydot and install graphviz (https://graphviz.gitlab.io/download/), ', 'for pydotprint to work.'). I installed pydot and graphviz through PyPI, and ran the test again. I got the same error.

2. I created another new environment and installed python 3.6.6. Tensorflow installation is fine. But when I installed desc, I failed to build wheels for louvain and igraph.

3. I created another environment and installed python 3.8.3. Tensorflow 1.7.0 installation failed.

4. I repeated the trial 1 as described above and build desc from scratch by downloading the repo. It threw me an error that pandas, matplotlib did not found. I installed pandas and matplotlib, and then re-installed desc. It threw me the same errors.

I wonder what Ubuntu version you were using when you tested desc on linux?

Many thanks!

graphviz need to install from ubuntu soft command.
apt install , or downlaod from graphviz website.
I have the same error in windows.

then pip install pydot ,ok

if not work, please update the conda
conda update conda
conda update anaconda
and pip
and must reinstall scanpy==1.5.1, if version >1.5.1,will not work
